Can someone help me with how to check and correctly adjust the fuel setting on my EJ 22. It has increasingly been ramping up to the worst today of around 30 ltrs for an hour.I checked the setting and am unable to determine if it has moved by sight.The air filter is clean and unblocked ,the prop is set accurately and the cruising revs haven"t changed? Apart from the ambient temp today at 1000 ft was 15 deg.instructions an a photo of what area to adjust, if relevent would be appreciated.Dave

just saw this............ej22 are injected yes, is yours carbed ???. If injected, then the pewtar ( soob pewtar set by soob ) handles all that mixture stuff. If.........it"s been running fine till now, then it ain"t getting accurate info from a sensor or 2. Getting 2nd hand sensors is easy, unusual for them to cak it......but happens One can also get your pewtar "fault diagnosed"......there will be a code it spits out for any faults. A good workshop can hook into it and get a readout. 2ndly there is a company melbourne way that you send your pewter to, they hook into it etc etc.Lastly.......some soob pewtars are are wrongly "tweaked" by folks to operate in open loop mode, not realising fuel burn is sky high as a consequence. For memory, not fitting an oxygen sensor is part of it..........i think.My own soob....ej25 EFI, is now burning around 20.....22L per hr.........with ALL SENSORS in the system. ( this fuel burn is averaged over, from MTOW to a lesser weight as fuel burns off during longer flites )

Switching from Carb to FI and NOT changing the prop I also got 100 extra engine rpm and of course no more carby ice as well as the fuel savings. Not often you get a win win win result!!!!Aussie Paul.

Thanks for your words and advice Russ and Paul.It is a fuel injected EJ 22 and it has averaged around the 18 ltrs to date.I"ll recheck the cables and connections in the sensor system and look for the obvious.

Hi Dave,Check the coolant temperature sensor , if this is faulty it will tell the ECU the engine is running too cold and increase the fuel mixture as it does on a cold start, Also if the thermostat sticks open and the coolant temp is too low the same thing will happen.Ray.

The thermostat and temp. senser can be checked in the old kettle, with an ohm meter on the senser. Whats got me stuffed at the moment is my ej25 subaru radiator has been replaced with a ford rad. after a stone incident, and now the thermostat wont open. The engine cools with no thermostat, but runs too cool (65 deg) The thermostat is at the bottom of the engine and relies on hot water coming from the heater hose
